The rate is based on a ceiling of 4.00 percent over the weekly average prime loan rate of 3.25 percent as published by the Federal Reserve on May 20th, 2013.

Gonzales said the rate remains in effect until the average prime loan rate as announced by the Federal Reserve Bank changes. Chapter 464, Public Acts of 1983, the legislation regulating interest rates in Tennessee, requires that the commissioner of Financial Institutions make an announcement weekly of the formula rate of interest.
